metrics
only.Descriptor contains all the settings that describe an instrument, including its name, metric kind, number kind, and the configurable options.
Implementations
impl Descriptor
[src]
pub fn new(
name: String,
instrumentation_name: &'static str,
instrumentation_version: Option<&'static str>,
instrument_kind: InstrumentKind,
number_kind: NumberKind
) -> Self
[src]
name: String,
instrumentation_name: &'static str,
instrumentation_version: Option<&'static str>,
instrument_kind: InstrumentKind,
number_kind: NumberKind
) -> Self
Create a new descriptor
pub fn name(&self) -> &str
[src]
The metric instrument's name.
pub fn instrument_kind(&self) -> &InstrumentKind
[src]
The specific kind of instrument.
pub fn number_kind(&self) -> &NumberKind
[src]
NumberKind returns whether this instrument is declared over int64, float64, or uint64 values.
pub fn description(&self) -> Option<&String>
[src]
A human-readable description of the metric instrument.
pub fn set_description(&mut self, description: String)
[src]
Assign a new description
pub fn unit(&self) -> Option<&str>
[src]
Unit describes the units of the metric instrument.
pub fn instrumentation_name(&self) -> &'static str
[src]
The name of the library that provided instrumentation for this instrument.
pub fn instrumentation_version(&self) -> Option<&'static str>
[src]
The version of library that provided instrumentation for this instrument. Optional
pub fn instrumentation_library(&self) -> &InstrumentationLibrary
[src]
Instrumentation library reference
pub fn attribute_hash(&self) -> u64
[src]
The pre-computed hash of the descriptor data
